How to prevent car fires? What fire-fighting devices/ equipment should be prepared daily?

Most car fires originate from circuits, fuel lines or high-temperature components coming into contact with flammable materials.

In daily life, we should prevent car fires from the following points:

1. Inspect fuel lines and circuits (for fuel vehicles):
1) Regularly check the engine compartment for oil leaks (gasoline/Oil), as this is the most dangerous fuel source.
2) Be vigilant about aged, exposed or privately modified (high-power audio systems, headlights) wiring, as this can easily lead to short circuits. 

2. Clean the engine compartment:
Regularly remove fallen leaves and oil sludge. The hot turbocharger or exhaust pipe can easily ignite dry leaves. 

3. Avoid storing hazardous items (General):
In summer, do not store lighters, power banks, carbonated beverages, or reading glasses (with focusing function) in the car. 

4. Special considerations for new energy vehicles:
1) Avoid any damage to the chassis (the battery pack is usually at the bottom).
2) Use original or compliant charging stations as much as possible to prevent overcharging and overheating during fast charging.
3) If the vehicle gets waterlogged, thoroughly inspect the battery pack. 

Which fire extinguishing devices are suitable for car fires?

For cars (not for households), depending on the vehicle type, the following recommendations are made:

1. Small passenger cars (private cars/SUVs)
Recommended equipment: Aerosol fire extinguisher.
Reason: Although dry powder fire extinguishers are inexpensive, they will severely corrode the wire connectors and paint surfaces in the engine compartment after spraying, and are difficult to clean. Aerosols are small in volume and have no residue, making them suitable for confined spaces.
Installation location: Under the driver's seat (not in the trunk). 

2. Operating Vehicles (Taxi/Van/Bus/Mechanical Construction Equipment)
Recommended Equipment: Vehicle-mounted automatic fire suppression device (fire detection tube type or temperature-sensitive type).
Function: Installed directly in the engine compartment or battery compartment. When there is an open flame or the temperature reaches the set value (such as 170℃), the device will automatically activate without the need for human operation. This is particularly effective for engine compartment fires.
